>Blackface is a form of theatrical make-up used predominantly by non-black performers to represent a caricature of a black person. The practice gained popularity during the 19th century and contributed to the spread of racial stereotypes such as the "happy-go-lucky darky on the plantation" or the "dandified coon".[1] By the middle of the century, blackface minstrel shows had become a distinctive American artform, translating formal works such as opera into popular terms for a general audience.[2
